I put a big picture on the background of the application, the application starts to slow down?

Question

Android

I add a picture to the window (1242x2208 and 62.84kb), the application immediately starts to slow down, if the picture is changed to a smaller one, everything works fine.
What could be causing this and how can I fix it?

Answer 1

Try to save the image in different resolutions and put drawable-ldpi, -hdpi, -xhdpi, etc. in different folders. How the device will not waste resources on scaling
